Journal ArticleDOI
Prenatal stress and the programming of the HPA axis
TL;DR: There is little evidence, so far, that altered function of the HPA axis in the child mediates the behavioural or cognitive alterations observed to be associated with prenatal stress.
Journal ArticleDOI
Prenatal stress and neurodevelopment of the child: focus on the HPA axis and role of the placenta.
TL;DR: The evidence for a similar mechanism in humans and how maternal stress may cause other changes in the placenta which affect fetal neurodevelopment is reviewed.
Journal ArticleDOI
Maternal prenatal anxiety and downregulation of placental 11β-HSD2.

TL;DR: Findings provide evidence for an association between prenatal maternal mood and downregulation of placental 11β-HSD2, the enzyme which metabolises cortisol, and support the hypothesis that this may be one mechanism underlying fetal programming by prenatal stress.
Journal ArticleDOI
Fetal Origins of Mental Health: The Developmental Origins of Health and Disease Hypothesis.
TL;DR: These findings parallel studies showing that antenatal maternal emotional well-being likewise predicts the risk for later psychopathology, and form the basis for integrative models of fetal neurodevelopment, which find little support for such integrated models.
Journal ArticleDOI
The persisting effect of maternal mood in pregnancy on childhood psychopathology
TL;DR: These analyses provide some of the strongest evidence to date that prenatal maternal mood has a direct and persisting effect on her child's psychiatric symptoms and support an in utero programming hypothesis.
